Rosalind Franklin, the British scientist whose research led to the discovery
of the structure of DNA, has been remembered with a Google Doodle.

Today is the 93rd birthday of the biophysicist and X-ray crystallographer, who helped discover DNA's structure but controversially missed out on a Nobel prize.

It emerged after her death that fellow scientists James Watson and Francis Crick used her data to help understand how DNA was put together.

Franklin died in 1958, only a few years before Watson and Crick were awarded the Nobel Prize for their work.

The second "o" in the Google Doodle contains an image of Franklin, while the "I" has been replaced with the DNA double helix.

The established view surrounding the crucial DNA discovery was that Crick and Watson were the greater scientists as they understood how DNA carries genetic information, where as Franklin’s crystallography images simply served as confirmation of what they already knew.

However, it’s subsequently been shown that it was Franklin’s data on the density of DNA and the dimension of the helix spiral which convinced Crick to start constructing the backbone of the successful DNA model. Another scientist, Max Perutz, had obtained Franklin's unpublished data without her knowledge.

Crick later wrote that “the data which really helped us to obtain the structure was mainly obtained by Rosalind Franklin”.

Franklin was born in Notting Hill in London on July 25, 1920. She died of ovarian cancer aged just 37.
